United States, residing at lhiffalo, in the eounty of Erie and State ofNew fork, have invented eertain new and useful Improvements inShaftbupports; and i do declare the following to be a full, elear. andexaet, de-

scription of the invention, sueh as will enable others skilled in theart to whieh it apperi-ains to make and use the same.

This invention relates to a thill support.

The objeet; of the invention is to eonstruet a deviee oi this eharaetm'from a. single pieee of stiff wire wit hout any bolts, nuts or sharpedges to mar the buggy. and

Which can be easily at taehed and detaehed wit heul the 1 use of toolsand which will hold the shafts in any desired adjusted position.

111 the accompanying drawings: Figure t represents a side elevation ofthe deviee applied; Fig. 2 represents set-tiring said U-shaped rollerbearing member to the it front elevation thereof; big. 3 represents aperspeetive view of the deviee detaehed in open position ready to beapplied; Fig. -t represents a perspeelive view of the roller detached;and l ig. 5 represents a perspeetive view of a modified form of theinvention. Fig ti rep resents a detail sectional view showing the-formillustrated in Fig. 5 applied.

is made from a. single pieee of heavy spring wire bent. intermediatelyto form an angular loop l to straddle the shaft Coupling ll. of theshaft 20. the straight. bar 2 of said loop being arranged to bearagainst the (lip belt 22 and hold it against rattling. The arms I) and tare bent or curved forwardly and are eoiled at 5 to form springs. Thesearms 3* and l are extended and the free ends (3 and 7 thereof are bentinwardly towards eaeh other to form a bearing for the roller ltl. metalStrap Sis secured to the arm 3. and has its free end bent to form a hook9 to detaehably engage the arm t and lock the bent ends 6 and 7 a instdisengagement from the roller 10. The roller l0 is preferably madespoolshaped with a deep groove, and the side flanges, as ll, beingeurved to provide for the riding of the roller over the bolt nuts on theshaft without. disengaging it, from the shaft.

In the use of the deviee above deseribed, the squared loop .lstraddlesthe shaft eoupling and the eurved bent When the shaft is lowered, theroller moves baek toward the shaft. eoupling and the tension of thespring \\'hen the shaft; is raised, the roller 10 moves forward making alonger leverage and deereasis inereased.

ing the tension of the spring.

ln the form shown in l whieh is designed for use on heavy shafts orthills sueh as wagon and eart shafts, thesupport is of the same general(onstrnetion as that shown in Figs. l to l, exeept that the arms 13 andH have their free ends unbent, and provided with a detaehahle tubularU-shaped extension member 25 lelest'opieally arranged thereon, the legs26 and 27 of the member 27 sliding on the arms l3 and ll of the springmember and the straight eonneeting bar 25 thereof serves as a bearingfor the roller Iii which is of the same eonstruet ion as the roller l(l. The free ends of the legs 2t; and 27 are provided with reinforcingeellars 2S and it) provided with set serews 30 and 5H for arms l3, and Hat any desired point. to lengthen and shorten said arms.

To give the additional strength required to uphold heavy shafts, anextra spring member is provided, whieh eomprists a U shaped member -10adapted to pass through the eoils l5 of the shaft-engaging member and isprovided at its free ends with serew threads, on \\'lil('ll are mountedthumb st'rews ll and 12 for adjusting the tension of the spring loop 45,\\'lll(ll is also made 1 approximately Usha', ed with its arms hi and i7eurved portion thereof extends bat-k underneath the axle with 1 theCoils, as 5, disposed over the axle. The hook f) of the clamping strap Sis disengaged from the arm =1, the

ends 0 and 7 sprung apart and passed under the shaft 1 as -13, which areslid-ably arranged on the member if). The straight bar -lZ eng ges andbears on the arms 3 and at near their points of eonneetion with thestraight bar 2 of the member lv l elaini as my invention l. r shaftsupport eomposed of a single piere of heavy spring wire bentintermedialely to form an angular loop to straddle a shaft eoupling withthe arms thereof bent at right angles to the loop and then extendedforwardly in :i eonti nious enrve and having eoils formed therein in poition to lie over the axle when applied. a roller delaehiiioitilletlbetween the ends of said arms and treat for loelaing said roller in posiion on said arms.

2. shaft support eomprising a single pi-ee of wire bent to form a loopto straddle a shaft eoupling and having spat-ed arms with formedtherein. a spool-shaped roller mounted hetween said arms with groovetherein and having t'ae inner faees of the side fl: thereof rurved toprovide for lhe riding of the roller over the bolt and :1 elai lpinginemher entlueeled with one arm and g'ing the other.
